Dr, T is an amazing doctor. She has literally saved my life. When I met her in January 2021 we had no idea what was wrong with me other than I was filled with cancer and didn’t know where the cause was. I couldn’t walk well at all - was having trouble breathing and was very scared. Six years later I am thriving living with Stage 4 Metastatic Breast Cancer all because of Dr. T and her physicians assistant Colleen Murray.

Dr. Theodoulou is the only physician that thoroughly reviews my medical chart for any tests, consult, pharmacy changes etc prior to my exam. She is very attentive to concerns, and provides a thorough exam. She truly is compassionate, professional and appears to take a genuine interest into the whole person. I appreciate and respect her professional expertise!!
